THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The chordae tendinae (CT) are strong, fibrous connections between the valve leaflets and the papillary muscles . These are attached to the leaflets on to the ventricular side and prevent the cusps from swinging back into the atrial cavity during systole.

Detailed explanation-2: -The AV valves are anchored to the wall of the ventricle by chordae tendineae (heartstrings), small tendons that prevent backflow by stopping the valve leaflets from inverting. The chordae tendineae are inelastic and attached at one end to the papillary muscles and at the other end to the valve cusps.

Detailed explanation-3: -The papillary muscles are muscles located in the ventricles of the heart. They attach to the cusps of the atrioventricular valves (also known as the mitral and tricuspid valves) via the chordae tendineae and contract to prevent inversion or prolapse of these valves on systole (or ventricular contraction).

Detailed explanation-4: -The bicuspid (mitral) valve complex of the human heart consists of functional units which include the valve leaflets, chordae tendineae and the papillary muscles.
